15 x 15 x 15" Double Wall Boxes

These 15 x 15 x 15 inch double wall corrugated boxes are built from ECT-48 kraft corrugated board — a two-layer flute construction that delivers substantially greater puncture resistance, compression strength, and stacking durability than standard single wall alternatives. The cube format distributes load evenly on all six faces, making it one of the more versatile configurations for heavy or irregular contents.

Applications include industrial parts shipping, dense retail goods, bottled products, hardware, and consolidated e-commerce orders where single wall board would compress or fail under load. The reinforced sidewalls hold up in palletized stacking environments and in transit conditions where boxes experience repeated handling or extended dwell time in distribution centers.

Boxes weigh approximately 2.31 lbs each, and ship flat to minimize receiving and storage space. Sold in bundles of 15 and rated parcel-friendly for standard carrier fulfillment.
